If you wish to maintain a considerable amount of bitcoin securely, it is smart to research how the wealthiest bitcoin holders deal with this job. Whereas wealth doesn’t trigger infallibility, these entities have essentially the most to lose from making a mistake. They need to be extremely motivated to place substantial thought and analysis into the safety of their bitcoin.
Figuring out the wealthiest bitcoin holders could be troublesome, and asking them to disclose the total particulars of their safety is unlikely to achieve success. Nevertheless, the bitcoin blockchain supplies us with some useful info. The transaction historical past and balances of all bitcoin addresses is publicly-available data.
What info can we collect?
If an entity (individual or group) owns plenty of bitcoin, it’s doable that they hold their bitcoin unfold throughout many alternative addresses, every with a smaller-sized stability. These addresses wouldn’t essentially stand out from the gang. In some instances, it’s unimaginable to affiliate completely different addresses with the identical pockets or proprietor. In different instances, affiliation between addresses requires blockchain evaluation, typically counting on superior methods and assumptions which aren’t assured to offer correct info.
Though it’s difficult to definitively determine the wealthiest entities by way of bitcoin, and exactly how a lot bitcoin they personal, it’s trivial to determine the wealthiest bitcoin addresses. There are just a few web sites that observe these addresses in actual time. The character of those addresses can present plenty of clues about how the bitcoin is secured.
For instance, if you’re accustomed to handle varieties, you’ll know that any handle that begins with a “1” is a P2PKH handle, and due to this fact have to be a singlesig association. Equally, any handle that begins with “bc1q” and has a size of 42 characters is a P2WPKH handle, and should even be a singlesig handle. Bitcoin held by considered one of these handle varieties isn’t using multisig safety. Utilizing SSS or MPC could be the one strategy to obtain institutional-grade safety, as mentioned in our article masking thresholds.
In the meantime, any handle that begins with a “3” is a P2SH handle. Any handle that begins with “bc1q” and has a size of 62 characters is a P2WSH handle. These handle varieties have the potential of using multisig. Nevertheless, solely after bitcoin has been spent out of those addresses will the custody construction be revealed. Some P2SH addresses are literally singlesig, a construction that was briefly standard whereas SegWit was being initially adopted. Due to this fact, if considered one of these handle varieties has by no means been spent out of, the custody construction is unknown.
Wanting on the information
Let’s check out the 81 addresses which every maintain greater than 10,000 bitcoin, as of January 30, 2024. Altogether, these addresses maintain greater than 2.5 million bitcoin.

*Probably misplaced
**Not utilizing MPC
Out of those 81 addresses, at the least six of them are holding bitcoin that’s more likely to be misplaced (179,302 BTC). These six addresses have been created by their homeowners in 2010 or 2011, when bitcoin had a a lot smaller worth and was not taken as significantly as it’s at this time. 5 of the six have by no means been spent from, and the opposite one made its final withdrawal in July of 2010.
The remaining 75 addresses use a wide range of custody buildings. Let’s break it down:
Tackle Sort |
Addresses (%) |
Whole Bitcoin Steadiness (%) |
Singlesig |
53 (70.7%) |
1,745,905 (67.6%) |
Multisig |
16 (21.3%) |
608,773 (23.6%) |
Unknown |
6 (8.0%) |
226,205 (8.8%) |
As defined in our article discussing institutional-grade threshold safety, it’s doubtless that the 53 singlesig addresses are utilizing both SSS or MPC. Two of the addresses, nonetheless, are unlikely to be utilizing MPC, as a result of they have been created earlier than 2018, when the first-ever MPC threshold protocols for ECDSA have been invented. It’s doable that these addresses are utilizing SSS as an alternative.
The 16 addresses that we all know are utilizing multisig have all been spent out of, and in doing in order that they have revealed their particular quorum construction. There’s a broad assortment of quorums:
- 4 cases of 3-of-5
- 3 cases of 2-of-3
- 2 cases of 2-of-2
- 1 occasion of 3-of-9
- 1 occasion of 4-of-8
- 1 occasion of 3-of-8
- 1 occasion of 4-of-6
- 1 occasion of 3-of-6
- 1 occasion of 2-of-6
- 1 occasion of 3-of-4
The two-of-2 quorums stand out as the one quorums within the record which don’t provide inherent safety from single factors of failure. Whereas a distributed 2-of-2 multisig can defend in opposition to theft, it requires different strategies to guard in opposition to loss (akin to every key utilizing distributed SSS or MPC shares). You possibly can learn extra about how completely different quorums defend from theft and loss to various levels, in our broader multisig article.
Conclusions
After wanting on the information, at the least one factor is evident. Among the many homeowners of the wealthiest bitcoin addresses—a few of whom embrace the largest cryptocurrency exchanges and even the U.S. Division of Justice—there isn’t any consensus on the perfect methodology to safe bitcoin.
A few of these entities use multisig addresses, with typical quorums like 2-of-3 and 3-of-5, however there are a number of uncommon quorums as properly. Many entities use singlesig addresses, which may very well be using SSS or MPC. The main points surrounding SSS or MPC threshold quorums are by no means publicly recorded on the blockchain, limiting the extent of this investigation. It’s doable that a few of these singlesig addresses aren’t using any threshold safety in any respect, which might imply that sure stashes of bitcoin at present price greater than $400M are notably under-secured.
As we coated in a latest article, multisig at all times has the next safety ceiling than singlesig. When a singlesig handle is used (as is the case with at the least 70% of the addresses holding greater than 10,000 BTC) there’s a missed alternative for extra safety. Whereas singlesig does present some advantages for spending comfort and transaction charges, one would possibly count on these advantages to be much less essential than safety, for an entity holding bitcoin price hundreds of thousands or billions of {dollars}.
The reality behind why singlesig addresses are so generally discovered on the prime ranges is unclear. It might quantity to an absence of schooling, or a historic lack of services leveraging the mix of SSS and MPC alongside multisig. Fortunately, Unchained has pioneered a easy path to entry these combos, unlocking the best ranges of safety obtainable. For personal wealth and enterprise purchasers, we provide a vault product constructed with a basis of multisig, and keys that may be unfold amongst institutional key brokers. Every of those key brokers can deploy their very own threshold safety utilizing SSS or MPC. E book a free session!
